No holes in a radeon 8500?

They make noise, too.

No holes in a radeon 8500?

Post by Mad Ad » Mon Dec 15, 2003 12:08 am

Now what? :(

I'm getting an order ready for various silent bits for my pcs but ive a problem with an 8500 (which is on my gateway pc and very important silent cooling wise since its on in the living room 24/7). All the silent vga kits I see are for either holed 8500s or the usual 9500s and over, and the zalman 17 seems to be for older cards (gf2s etc) with nothing for an 8500 without holes.

It did cross my mind strapping it up with an 80mm ngml or L1 (whichever comes first in the post) ... mebee getting something smallish (zm47J chipset cooler?) and gluing it on with arctic epoxy too? I've got to do something about it soon cuz after a while hearing the fan uttering throes of death noisies, it stopped the other day - a bit of graphite worked for now but its still grumbling a bit.

Thanks for any suggestions guys

Perhaps glue a Zalman NB heatsink on it and if nessecary put a large undervolted fan on a bracket over the card to cool it down?
Lots of people have done similar things. Do a few searches in the VGA section to get loads of ideas.

I've done it two different ways with 8500's:

1) Zalman ZM-17 with an 80mm 5V L1A on a Zalman bracket.

2) Leave stock HS on card but remove the fan and use an 80mm 5V L1A on a Zalman bracket.

In one of my home gaming rigs I use the Zalman ZM-17 on a retail Radeon 8500 128MB, along with the Zalman bracket and an 80mm fan running at just under 5V (not a Panaflo L1A fan, which I find to be too noisy for my quiet systems).

Has run great for years this way. I even used to turn off the overhead fan, but I leave it on now just for peace of mind as other family members use the rig for gaming quite a lot nowadays.

Hi all, thanks for the replies.

Im not sure id trust the sink on it alone, its a puny little silver box, nothing more, not even fins on it, thats why I thought mebee a chipset cooler or something cheap (ive got arctic epoxy already) and easy to obtain? (especially since my cool parts order of bits i want is already £120 without including another psu or a zm17)

Ive got a couple of flos and papsts on the way to evaluate so im glad to hear the zm17 works, thanks for letting me know it is ok - zalman seem to forbid it - does the zm17 get very hot? Have you done a touch test to see how far hot heat went along it? Im wondering if even its too much?

What is the ZM-17?
I guess it is some kind of heatsink 17mm tall.
It is not listed as a product on Zalmans site.

*bonk* Ofcourse! Thanks for bringing my mind back...

The name is ZM17-CU to be exact.

From the looks of it the base is aluminium and the fins copper.
Isn't this really strange as it is the opposite of how good CPU coolers are made?
Shouldn't reversing the materials provide better cooling and lower manufacturing costs?

Thats the one - it looks huge compared with what is on there now (a very minimalist metal cage around a nearly dead fan)

The picture doesn't show it very well, but the center of its base (in middle picture) should look more coppertone as well as it receives all those copper fins...

Use the stock heatsink and fan, but put a resistor on the fan. It will be inaudible and run fine using a .. hmm.. I think I used a ~22ohm resistor...

That's what I did.

I would but the fans about to keel over - Ive heard its death rattle already and only the god that is 3in1 has protected it thus far.
